fMRI Preprocessing
fMRI data preprocessing is done in order to enhance the data and remove artifacts from the images extracted. It can include spatial and temporal adjustments and happens in multiple steps:
Realignment, Slice-time Correction, Coregistration, Segmentation, Normalization/Warping and Smoothing.
These steps do not necessarily happen in the given order, in fact, the ordering can vary given the data, the experimenter or the pipeline used. For an overview on each of the preprocessing steps, please view Andy's Brain Book. Here, we will describe a standard procedure used in the lab that can and should be adapted depending on the needs.
